I already know that the feature was removed because too many basic users broke Firefox by disabling it accidentally.

I know that I can do it by changing javascript.enabled in about:config but it's too dangerous if you want to do it often.I know that convenient extensions for Firefox like Noscript and others exists to do it, but I don't trust and don't want to manage yet another extension.And it seems to me such a basic feature for a web browser that I think Firefox is not complete without it.

So I suggest this :To include the javascript disabling option, not in Preferences or Options, but in the "Permissions" tab of the "Page Info" dialog and in the permissions manager "about:permissions".

The permissions system that introduced the feature to block images, cookies or plugins site-by-site is great.But how does it make sense to disable Flash, Cookies or even Images for an undesirable or dangerous website but not be able to disable javascript the same way ?

This way would also be an upgrade over the previous situation, because users would have site-by-site control with the option.And don't tell me basic users would again broke Firefox, because blocking Cookies and Images can broke a website just as well.

I hope that if someone who can do a thing about it read this, he or she would take it under consideration.

Thank you, I didn't know about the option being in the developer tools, I didn't scroll down in the advanced section, I learned something today.I think that's great for the option to be included without third-party extensions.

I still think the javascript permission would be a great addition, its place is right there with the cookie, images and plugins permission.

For posting in a mailing list, I thought about it, but didn't really know in which one since a lot of forum threads around the web give different addresses.If someone could guide me in the right direction I would gladly post it in the appropriate mailing-list.

Sure, but so are images, cookies and other stuff in the View Page Info, yet they're there to be overridden. The suggestion would be akin to the Yesscript extension. Yeah, you could just install that extension, but the suggestion seems to be a logical extension of what's done with images, cookies, popups and other items in the site permissions.

Thanks Manuel. I'm using your PrefBar extension for years (I think since Mozilla Suite 1.0) and just updated to the new 6.3.0 release (seem to have missed it), so thanks for the continued support to keep the extension working. I noticed that you've added Australis support, so thanks for that!

The code I posted above is based on what you use in your extension.

Could you consider to use this code in buttonCommands.js as that will make it possible to only set the width or height?
